org.jgrapht.event

Interface GraphListener<V,E>

Type Parameters:

V - the graph vertex type

E - the graph edge type

All Superinterfaces:

EventListener, VertexSetListener<V>

All Known Implementing Classes:

ConnectivityInspector, JGraphXAdapter, NeighborCache

public interface GraphListener<V,E>
extends VertexSetListener<V>

A listener that is notified when the graph changes.

If only notifications on vertex set changes are required it is more efficient to use the VertexSetListener.
